Since simple mobile tools will soon become a spyware and I use 3 of their apps regularly, yesterday I installed F-Droid after reading many Lemmy recommendations.
Wow, I'm pleasantly surprised.
A new app I've tested is Spotube (Spotify open source alternative; edit: apparently it uses Spotify metadata but it streams from YouTube. My bad.).
I use it because it moves a lot of settings into the sync jobs.
So now I can set individual sync jobs to only run on my home wifi and ac power, and other sync jobs (like my photos) to sync over any network and any power state.
